Search on surfaces: Exploring the potential of interactive tabletops for collaborative search tasks

Collaborative information seeking often takes place in co-located settings; such opportunities may be planned (business colleagues meeting in a conference room or students working together in a library) or spontaneous (family members gathered in their living room or friends meeting at a café). Surface computing technologies (i.e., interactive tabletops) hold great potential for enhancing collaborative information seeking activities. Such devices provide engaging direct manipulation interactions, facilitate awareness of collaborators’ activities, and afford spatial organization of content. However, current tabletop technologies also present several challenges that creators of collaborative information seeking system must account for in their designs. In this article, we explore the design space for collaborative search systems on interactive tabletops, discussing the benefits and challenges of creating search applications for these devices. We discuss how features of our tabletop search prototypes TeamSearch, FourBySix Search, Cambiera, and WeSearch, illustrate different aspects of this design space.     

Tomorrow we live: fascist visions of education in 1930s Britain

The present paper explores the fascist vision for education in 1930s Britain through the presentation of extracts from official publications of the British Union of Fascists (BUF), as well as from the writings of Party members. The paper presents a socio‐historical study of British adherents to fascism and provides an account of their thinking in relation to education and schooling, exposing a milieu of ideologues, Party functionaries and serving teachers who were animated by their political commitment. Following a brief outline of the early years of British fascism, there is an account of some key members and their educational ideas, followed by a discussion of the BUF’s educational policies and of its approach to internal education and training. The orientation of the BUF and its membership to education, and the Party’s formulated policies in this field present a modernist vision that was calculated to have particular appeal to educational professionals. There is a consideration, through memoirs, of the experiences of two BUF members who were teachers. The paper reveals a relatively hidden episode in the social history of British educational politics; one that contained paradoxes of intent and outcome, and of means and ends, when ostensibly progressive and socially elevating concepts were employed in ways that had an ultimately destructive impact on individuals, both personally and professionally, as well as on whole societies.

When information wanted to be free: Discursive bifurcation of information and the origins of Web 2.0

In the 1990s the aphorism “information wants to be free” reigned supreme, limiting our thinking in consequential ways. In actuality this aphorism was a fragment of a much more nuanced statement by Steward Brand, who also talked about “information wants to be expensive.” It seemed for quite a while that there was no resolution to the contradiction: information as both free and expensive. Eventually Web 2.0 resolved this contradiction by providing an architecture where information could be both free and expensive. Web 2.0 was not a product of technological advances: social media, wikis, big data platforms, and so forth. It was borne out of the understanding that free information on media platforms could yield profitable data on users. This article lays bare the discursive moves through which this understanding came about.

A near‐peer (NP) teacher discussing structures of the head and neck region with first‐ and second‐year students in the anatomy laboratory at Brighton and Sussex Medical School. NP teachers are fourth‐year medical students who elect to teach in gross anatomy practical classes delivered to first‐ and second‐year medical students. Evans and Cuffe discuss design, implementation and outcomes of the NP teaching program in the current issue of ASE.     

Physiological Effects of Deep Water Running following a Land-Based Training Program

Abstract

The purpose of this study was to examine differences in knowledge representation and problem solutions in expert and novice youth baseball players. Ninety-four players in two age divisions, 7–8 years of age and 9–10 years of age, were assigned to three levels of expertise: high; average; and low skilled. Each subject participated in an interview session to elicit knowledge representation and solutions to five different defensive game situations. Interviews were transcribed and analyzed for content, solution to the problem, errors in problem solution, and qualitative trends. The frequency of advanced solutions to each of the five situations were analyzed in separate chi-square tests for age and expertise. Differences among the levels of expertise were found for the accuracy of solutions to three complex situations. Age was significant for only one situation. Patterns of knowledge content accessed during advanced and less advanced responses indicated both experts and novices were in a beginning stage of developing baseball knowledge structures. Errors in problem solutions indicated children had difficulty monitoring critical conditions and making correct inferences. Players' and teammates' ability to execute baseball skills seemed to influence the content and structure of tactical knowledge accessed during problem solution.     

Physically abused children's regulation of attention in response to hostility

The present study examines the effects of early emotional experiences on children's regulation or strategic control of attention in the presence of interpersonal hostility. Abused children's reactions to the unfolding of a realistic interpersonal emotional situation were measured through multiple methods including autonomic nervous system changes and overt behavioral performance. Although physically abused and non-physically abused 4-year-old children did not differ in terms of their baseline levels of arousal, marked differences in physically abused children's regulatory responses to background anger emerged. These data suggest that the emergence of anger leads to increases in anticipatory monitoring of the environment among children with histories of abuse. Results are discussed in terms of risk factors in the development of psychopathology.     

When induction meets memory: evidence for gradual transition from similarity-based to category-based induction

The ability to perform induction appears early; however, underlying mechanisms remain unclear. Some argue that early induction is category based, whereas others suggest that early induction is similarity based. Category- and similarity-based induction should result in different memory traces and thus in different memory accuracy. Performing induction resulted in low memory accuracy in adults and 11-year-olds, whereas 5-, and 7-year-olds were highly accurate (Experiment 1). After training to perform category-based induction, 5- and 7-year-olds exhibited patterns of accuracy similar to those of adults (Experiment 2). Furthermore, 7-year-olds, but not 5-year-olds, retained this training over time (Experiment 3). With novel categories, even adults performed similarity-based induction, exhibiting high memory accuracy (Experiment 4). These results suggest a gradual transition from similarity- to category-based induction with familiar categories.     

Teaching writing: A situated dynamic

The paper is theoretically grounded in Cultural Historical Activity Theory, which holds that human development is founded within participation in social and cultural practices. In particular, the teaching of literacy is shaped not only by the curriculum as designated by policy makers and the institution in which it is located, but also by the individuals' understanding of what literacy and learning involves and how they act to achieve their goals. The paper explores data from a project that investigated the relationship between classroom talk and the teaching of writing in six early‐years classrooms. Participants' own understandings of teaching and learning need to be taken into account by researchers and policy makers. Cultural Historical Activity Theory has been used to explore the dynamic relationship between activity at societal, institutional and individual levels. It is argued that researchers and policy makers need to take account of the wider socio‐cultural context in planning and evaluating curriculum development initiatives.
